SANTA ANA — A Southern California swim instructor has been sentenced to 16 months in state prison for sexually assaulting two teenage girls he met through coaching, according to published reports Wednesday.

Todd Robert Sousa pleaded guilty in June to six felony counts of lewd acts upon a child and one felony count of unlawful sexual intercourse.

The Orange County District Attorney’s office says Sousa was accused of assaulting two 15-year-olds at a hotel four years ago. He had sex with one of the victims after she turned 16.

In a separate case, Sousa pleaded guilty in October 2011 to 13 felony counts of lewd acts on a child and three counts of unlawful sexual intercourse.

Prosecutors say in that case, he sexually assaulted a 15-year-old in an office, an equipment closet and in his car.

The 39-year-old co-owned and taught at Laguna Hills-based Swim Venture.
